heads up: porting libyui-qt to Qt5
by Martin Vidner 25 Jan '14

25 Jan '14

Hi, this is an early warning. I am porting the Qt backend from Qt4 to Qt5. In openSUSE, Qt5 is in the main repository since 13.1 and available in the OBS repository KDE:Qt5 for older releases. For other distributions, please check that you have Qt5. (Distrowatch shows me Qt4 for Mageia Cauldron, but then so it does for openSUSE Factory) If you are curious, look at https://github.com/mvidner/libyui-qt/tree/qt5-port (rebases are likely) -- Martin Vidner, Cloud & Systems Management Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu

bindings and casts
by Angelo Naselli 24 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I experienced problems by using YEvent, YItem and Cell access in YTable. The big problem in perl bindings is to get the cast from Yitem to YtableItem, as well as from YEvent to YXXXEvent. But also accessing to to Items by using childrenBegin and childrenEnd, there is no way to increment the iterator. http://www.swig.org/Doc1.3/Perl5.html#Perl5_nn18 says that there is a way to add functions to do that, indeed I used to implement all the cast i needed in my external widget plugin. I wonder if we can study a way to get rid of this problem? I don't know if ruby and python are also affected.

YTree and first YTreeItem selected
by Angelo Naselli 19 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Am I wrong or YTree does not honor the selected item? At a first look i thought it was because YSelectionWidget select the first item but does not look for children if they are selected so the first item remains selected. But i tried to set a root item (not the very first one) and i got that is always the first the selected. Any help?

Yitem and data pointer
by Angelo Naselli 12 Jan '14

12 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I don't knof if it is an issue or if i made a mistake but Ytem docs says /** * Set the opaque data pointer for application use. * * Applications can use this to store the pointer to a counterpart of this * tree item. It is the application's responsibility to watch for dangling * pointers and possibliy deleting the data. All this class ever does with * this pointer is to store it. **/ void setData( void * newData ) { _data = newData; } /** * Return the opaque data pointer. **/ void * data() const { return _data; } So Applications can use data pointer to manage additional information that can be retrieved after, when the item is selected maybe. I'm sure enough that data pointer is used by QT YTable implementation and YTree one, and probably also in gtk. That means that data pointer is not usable at all. To argue that, taking as example ManyWidget code: std::string TEST = "Test string"; YItemCollection items; auto t = new YTreeItem( "Item 1" ); t->setData((void*)TEST.c_str()); YItem *it = t; std::string st = (char*)it->data(); std::cout << "---------------- " << st << std::endl; items.push_back( t ); [...] tree->addItems( items ); st = (char*)it->data(); std::cout << "---------------- " << st << std::endl; First cout prints correctly Test string while second one, crashes in gtk while prints random data in qt (probaly the QTxxxxItem implementation pointer). So that seems to say data pointer is not for applications. WDYT?
